The Raiders have spent this offseason addressing primarily the defensive side of the ball.

Wednesday, they looked at offense, reportedly working out quarterbacks Seneca Wallace and Tyler Thigpen and running backs Bernard Scott and Rashad Jennings.

Wallace, who was out of football last season, will sign with the Raiders, according to reports.

With the recently-acquired Matt Flynn due to make a guaranteed $6.5 million as the presumptive stater, Wallace would seemingly compete with Terrelle Pryor for the backup job. In essence, it shows where the Raiders' collective head is when it comes to the quarterback position -- they want mobile, accurate signal callers who can run when the pocket breaks down.

The 5-feet-11, 196-pound Wallace has appeared in 62 games in his NFL career, which began as a fourth-round draft pick of Seattle in 2005, and has started 21 times. His record as a starter is 6-15 and he has won once since 2008.

But he is a cost-effective veteran presence -- what, Vince Evans was busy? -- needed in the Raiders' QB room as he has thrown for 4,808 yards in his career on a 59.2 completion percentage with 31 touchdowns and 18 interceptions and an 81.3 passer rating.

Wallace spent the first five years of his career with the Seahawks before moving onto Cleveland for two years in 2010.

Of course, if the Raiders draft a quarterback, all bets are off.
